The role

Job title: Research Engineer, High-fidelity simulations of ammonia/hydrogen combustion (RE1)

The primary objective of this position is to support the development, implementation, and validation of tabulated chemistry models for high-fidelity simulations of ammonia/hydrogen combustion under gas turbine conditions. The work will combine chemical kinetics, computational fluid dynamics, and high-performance computing, contributing to simulation tools suitable for modern supercomputing architectures, including GPU-accelerated systems.
The successful candidate will join the Propulsion Technologies Group within the CASE Department at the Barcelona Supercomputing Center (BSC). The group brings together researchers with multidisciplinary expertise in computational fluid dynamics, combustion, and high-performance computing, and participates in European and industrial projects addressing advanced propulsion and energy technologies.

Ammonia and hydrogen are promising carbon-free fuels for gas turbine applications. Their use introduces combustion challenges related to flame stability, ignition, fuel flexibility, and pollutant formation. Accurate numerical modelling is essential to understand these processes under the elevated pressures and inlet temperatures characteristic of gas turbine operation and to support the development of efficient combustors with low pollutant emissions.
Tabulated chemistry offers an efficient approach to representing complex chemical kinetics in large-scale simulations of turbulent combustion. Applying these methods to ammonia/hydrogen mixtures requires models that capture the effects of fuel composition, operating conditions, and turbulence-chemistry interactions on flame behaviour and emissions.

What you'll do

  • Generate and analyse chemical databases for ammonia/hydrogen mixtures over a range of pressures, inlet temperatures, fuel compositions, and equivalence ratios relevant to gas turbine operation.
  • Support the development and implementation of tabulated chemistry models within the computational fluid dynamics framework Alya.
  • Assess the ability of the models to predict flame behaviour and pollutant formation, including nitrogen oxides and unburned ammonia.
  • Perform and analyse numerical simulations of ammonia/hydrogen combustion, investigating the influence of operating conditions and fuel composition on combustion performance.
  • Document developments and results, and contribute to technical reports, scientific publications, and collaborative project activities.

How you'll work

  • The position will be located at BSC within the CASE Department
  • Duration: Open-ended contract due to technical and scientific activities linked to the project and budget duration
  • Starting date: 16/12/2026
